Tina Turner has married her long-term partner Erwin Bach in a low-key ceremony in Switzerland.

The Simply The Best hitmaker, who became a Swiss citizen in April, and her 57-year-old record executive hubby wed on the banks of Lake Zurich ‘a few days ago’ according to a municipal official.

The couple are now planning an intimate bash and Buddhist ceremony to celebrate their union at their Kusnacht house this weekend.

Music superstars including David Bowie and Sade are due to attend, along with television talk show queen Oprah Winfrey, according to Swiss weekly Schweiz am Sonntag, which also reported guests were requested to wear white.

Swiss media reported that a small stage would be set up for Sunday’s party, and that Turner and Bach had sent out letters to their neighbours apologising in advance for the noise they might cause.

The 73-year-old has been dating Bach since the 1980s.

She left her first husband, musical partner Ike Turner, in 1978 after years of abuse.
